Hi Victron Community,
I am currently setting up a grid parallel ESS with a Multiplus 2, a Venus GX and two 5KWh Tesla (24V each) Modules in series. I will setup a BMS (SimpBMS) for the Batteries in the future but would like to use them beforehand (with restricted parameters of course to ensure that they don't under and overcharge ).
I am struggling to find a battery option in VE-Config and on the Venus Remote to tell the multiplus to charge/discharge the batteries according to voltage. All options in the ESS Assistants appear to be requiring a BMS communicating to the GX/Multi that batteries are charged/discharged.
Isn't there a simple option where I can set the Multiplus to charge the Batteries up to 48V max and invert down to 38V, for example?
After starting the ESS Assistant I have changed the inverter and charger settings in Ve-Config manually to the above (38V - 48V), but the system does not engage and appears to be waiting for a signal from a (non-existent) BMS.
Is there a "BMS off" or "No BMS" function (or similar) on the GX that I have overlooked? Any help would be much appreciated.
Schematics of my setup are below:
